DESCRIPTION
The BUL1203E is a new device manufactured
using Diffused Collector technology to enhance
switching speeds and tight h
FE
range while
maintaining a wide RBSOA.
Thanks to his structure it has an intrinsic
ruggedness which enables the transistor to
withstand a high collector current level during
Breakdown condition, without using the transil
protection usually necessary in typical converters
for lamp ballast.
